Look up bilateral filters and the various papers related to minimizing sharp segmentation.
- AstralStorm 7y agoIndeed, a bilateral filter is this approach of selection but segmenting on signal statistics of the surrounding image rather than just value. (Usually variance for denoising, contrast for non-blocking sharpening, L2 metric like PSNR for deblocking, luminance for chroma artifact reduction after upscaling.)
- BubRoss 7y agoCan you link some papers that take about this? Segmenting on statistics isn't typical in the many papers I've read.
